cannibal corpse

Out of the few songs I've heard from Cannibal Corpse, none seem to really have content...just a guy that sounds like he has a cold coughing into the mic, while a few chords play in the background...occasionally a bit of actual guitar play.

 Have I only scratched the surface, and not seen the beauty inside...or do they just suck? I have an open mind, but I'm really starting to close it to them.
